When you look at a clear blue sky you see tiny specks and hair like structures floating in your view, called "floaters" This is basically.

Options

A. Interference pattern
B. Diffraction pattern
C. Emission spectra
D. Absorption spectra

Answer

To understand the phenomenon of "floaters" that we see in a clear blue sky, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Floaters**: Floaters are tiny specks and hair-like structures that are visible in our field of vision, especially against a bright background like a clear blue sky. They are not objects in the sky but rather shadows cast by tiny particles within the vitreous humor of the eye.

2. **Light Interaction with Particles**: When light from the sky enters our eyes, it interacts with these tiny particles. The interaction can lead to various optical effects, including scattering and diffraction.

3. **Scattering of Light**: The blue color of the sky is primarily due to Rayleigh scattering, where shorter wavelengths of light (blue) are scattered more than longer wavelengths (red). This scattering is what makes the sky appear blue.

4. **Diffraction of Light**: As light passes around the floaters (which can be tiny cells or fibers in the vitreous humor), it can bend or spread out, creating a diffraction pattern. This diffraction can enhance the visibility of the floaters against the blue background.

5. **Conclusion**: Therefore, when we observe floaters in a clear blue sky, we are witnessing the effects of light scattering and diffraction caused by tiny particles in our eye, rather than interference patterns that are typically associated with wave optics.
